SAW-TABLE.

SPECIFICATION forming. part of Letters Patent No. 415,435, datedNovember 19, 1889.

Application filed April 8, 1889. Serial No. 305,820. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH M. BAKER, of Louisville, in the county ofJefferson and State of Kentucky, have invented a new and usefulImprovement in Saw-Tables, of which the following is a specification.

My invention is an improvement in sawtables, and relates particularly tothe mechanism by which the material to be sawed may be automatically fedto the saws, and suitably supported to facilitate such feeding; to whichends the invention consists in certain novel constructions andcombinations of parts, as will be hereinafter described, and pointed outin the claims.

In the drawings, Figure 1 is a top plan view of a saw-table providedwith my improvements. Fig. 2 is a side view of same, partly broken awayto show the eccentrics and part of the rod connecting the same with thefeedslide. Fig. 3 is a detail view of the top of the saw-table with theseveral board holdin g and feeding devices removed. Fig. 4 is a detailperspective view of the table-top with the several parts in operativeposition, and Figs. 5 and 6 are detail views.

The framing supporting the table-top A may be of any suitableconstruction, and has bearings for the shafts C and D, the former Csupporting the saws E, which may be crosscut or rip, and the latter Dsupporting the eccentric F. The shafts C D are connected by a belt, soone may be driven from the other. An idler G is usually provided, bywhich the belt may be tightened up or slackened, so that the operationof the eccentric and the feed resulting therefrom can be started orstopped at any time desired. The eccentric F is formed with a slot f,receiving the shaft D, on which shaft is secured a sleeve (7, having ashoulder (1, against which one side of the eccentric disk bears, aclamping-nut D being threaded on the said sleeve and bearing against theopposite side of the disk from shoulder d, and serving to secure it inany desired radial adjustment on the shaft. It will be understood thatby setting the eccentric off the center more or less the length ofstroke of the feed-slide may be varied to suit the width of the boardsbeing out. It will be seen that the sleeve (Z is formed with a portion(P, which fits in the slot f of the eccentric, such portion (1 beingformed between the shoulder d and the outer threaded portion d of thesleeve. 7

The table-top is slotted at H, to form a guide for the feed-slide I,which has a portion 1' fitting in said slot and connected with one endof the rod'J, the opposite end of which connects with the strap or ringF on the eccentric disk F. By this construction the turning of shaft Doperates to move the feed-slide back and forth, its forward movementfeeding a board to and through the saws, and its backward movementreturning it for the next board.

To hold the boards to be sawed, I provide a hopper K, having a frontplate or section L arranged immediately in rear of the saws, a backplate or section M arranged a sufficient distance from plate L to permitthe boards to fit between them, and a gage plate or section N arrangedat one side of the saw-table top,-

and spring-holders O 0 arranged at the side opposite plate N, all ofwhich will be, described more in detail. The front section L has itslower edge arranged sufficiently above the top of the saw-table topermit a board or boards to be fed forward under it. This section L isvertically adjustable, so its lower edge may be set higher or lower, topermit the feeding of boards of different thickness, or of two or moreboards, as desired, a feed-slide of suitable thickness being provided.

To enable the adjustment of the section L, I provide at its lower edgelugs I, through which project threaded studs L, mounted on the table,and nuts Z Z, turned on the said studs above and below the lugs Z,enable the section L to be set to and secured in any desired verticaladjustment. Manifestly this section L may be adjusted vertically bydifferent constructions from that just described, and I do not desire inthe broad features of my improvements to be limited to the particularconstruction of the adjusting devices as shown. The rear section M ishinged near its lower edge, so it can be thrown back, to facilitate thefilling of the hopper, and is adjustable toward and from the frontsection L. In securing this adjustment of section M the saw-table top isformed with slots m, and the fastening-screws 'm of the section M passthrough these slots and receive the thumbnuts m turned on these screws,as shown. By the described adjustment the hopper may be fitted toreceive wide or narrow boards.

The side guide or gage N is adjustable laterally, so as to hold theboards at one end in the desired relation to the saws, this adj ustmentbeing secured by passing the screws 42, which fasten such guide N to thetable-top, through slots n in said top, as shown.

At the side of the table-top opposite the gage-plate N, I arrange thespring-holders O, which comprise spring-plates 0 and the vertically androtarily adjustable bolts 0', having slots 0 in which plates 0 are heldby nuts 0 The spring-plates 0 bear against one end of the boards to besawed and press them at their opposite ends snugly against the guide orgage N. By turning the bolts 0, and by setting the spring-plates indifferent longitudinal adjustments within the slots 0 the tension ofsuch springs may be regulated as desired. From the foregoing it will beseen that the hopper is adjustable both as to length and width, so thatit may be set to any desired length or width of board, and by having itsfront plate or section adjustable vertically at its lower end the hopperis also fitted topermit the feeding of thick or thin boards and one ormore at a time.

To hold the boards down when in contact with the saws, I providepressers P P, consisting of spring-plates secured at one end to blocksP, fitted and adjustable rotarily and longitudinally along a rod q,formingapart of a frame Q, mounted on the saw-table near its front end,clamping-screws 19 serving to hold the springs in any adjustment. Thesprings P extend at their free ends'to a point slightly in advance ofthe front plate of the hopper, and have such ends bent or curved upwardsufiiciently to permit the boards to be forced by the feed-slidethereunder.

Having thus described my invention, what I claim as new is 1. In asaw-table, the combination, with the saws, of the hopper having at oneside a plate N, adjustable laterally and provided at its opposite sidewith a spring presser or pressers 0, adj ustably supported, wherebytheir tension may be adjusted to correspond with the adjustment of plateN, substantially as set forth.

2. In a saw-table, the table-top A, having longitudinal slots m andtransverse slots n, combined with the hopper having a front, side, andback plate, the screws securing such side plate and passed .throughslots n, and the screws securing the back plate and passed through slotsm, all substantially as set forth.

3. In a saw-table, the combination of the table-top, the saws, thefeed-slide, and the hopper having its'pla'te M hinged at or near itslower edge, whereby it may be turned down at will to permit access tothe hopper from either side, all substantially as and for the purposesset forth.

4. In a saw-table, a hopper having its front plate L provided with lugsZ, the table-top,

thethreaded studs L, mounted on said top and extended through lugs Z,and nuts on the said studs above and below the lugs Z, all combinedsubstantially as set forth.

5. In a saw-table, the combination of the table-top, the hopper havingits side plate N adjustable laterally, the bolts 0, arranged oppositeplate N, adjustable longitudinally and rotarilyand provided with slotsoand the spring-plates fitted and secured in said slots, substantially asset forth.
